NORTON, Mass. — Rory McIlroy got the start he wanted yesterday at the Deutsche Bank Championship, erasing a three-shot deficit in just five holes. The finish was hardly a masterpiece, except for the part when golf’s No. 1 player posed with the trophy.

Boy Wonder didn’t make it easy on himself on Labor Day at the TPC Boston. He tore up the turf on a tee shot that traveled 170 yards, and that was the only fairway he hit over the last five holes.

He had to make a 6-foot putt to save par from a bunker, and a 5-foot putt to save bogey after a pitch sailed from one side of the green to the other. And he had to wait as Louis Oosthuizen’s birdie putt to force a playoff slid below the hole.

“I had a couple of wobbles coming in, but I obviously did enough and I’m very excited to get a victory,” McIlroy said.

That’s all anyone will remember.

On a leaderboard packed with some of the biggest names in golf — McIlroy, Oosthuizen, Tiger Woods, Phil Mickelson and Dustin Johnson — the 23-year-old from Northern Ireland took a giant leap toward establishing himself as the best in the game.

With four birdies in six holes at the start, and limiting the damage from his mistakes at the end, McIlroy closed with a 4-under 67 for a one-shot victory over Oosthuizen, joining Woods as the only three-time winners this year on the PGA Tour.

McIlroy goes to No. 1 in the FedEx Cup. And with one of his wins being the PGA Championship, that might be enough for his peers to vote him PGA Tour player of the year. He also has a comfortable gap in the world ranking, and could be tough to catch the rest of the year unless Woods were to win the next two FedEx Cup events.

“He’s not No. 1 in the world for nothing,” Oosthuizen said. “He’s a great young talent, a lot of majors left for him to win. He’s such a cool kid on the course. It’s great playing with him. He makes tough shots look really easy sometimes, especially long irons.’’

Woods made an early charge to get back in the hunt, though he never got closer than three shots until a two-putt birdie on the par-5 18th gave him a 66. He finished in third place, two shots behind, and earned enough money to become the first player to surpass $100 million in PGA Tour earnings.

Woods attributed that to higher purses, though he’s responsible for those.

“I think we got some interest in the game of golf,” Woods said. “A lot more youth, that’s for sure.”

One of those kids — McIlroy — keeps winning. The Honda Classic in March. The record eight-shot win in the PGA Championship. And now a FedEx Cup playoff event in Boston.

“Three is a great number,” McIlroy said. “I’d like to make it four — or five — after the FedEx Cup.”

Mickelson also had a 66 and tied for fourth, along with Johnson, who had a 70 and likely played his way onto the Ryder Cup team. Brandt Snedeker made a strong case for a captain’s pick with a 65-67 weekend to finish sixth.

Davis Love III will announce his four picks this morning in New York.

There was other drama at the Deutsche Bank Championship, though it was not nearly as compelling as the top of the leaderboard.

Charley Hoffman went from the first page of the leaderboard to an unimaginable collapse until he steadied himself at the end. Hoffman, who was 13-under after a birdie on the eighth hole, played his next nine holes in 8-over par, including a quadruple-bogey 7 on the par-3 11th. He came to the 18th needing a par to finish among the top 70 in the FedEx Cup and advance to the third playoff event next week in Indianapolis.

He went over the green in two, barely chipped onto the putting surface, and then ran his putt 12 feet by the hole. He made the putt for par, and moves on.Others who advanced included Dicky Pride, who birdied his last two holes to get the 70th spot by one stroke over Jonas Blixt; and Chris Kirk, who stumbled at the start only to birdie four of his last five holes
